CR52-M: CDRW ramps up to 32X

Write Speeds
Moving on, we take a look at CDR write benchmarks:

The average write speed came to about 39.23X. While many drives perform upwards of 40X average write speeds on this benchmark, realistically, the second or two differences will not matter.

The CR52-M uses a magnetic head based on Partial CAV for the rewrite mode. The drive is locked to prevent the unit from producing a greater than 32X rewrite speed after it is obtained on CAV. Below are rewrite and write specs based on the same benchmark.
| Average Transfer | Media Length | |
| PNY 52X CDR Data CD | 39.32X | 79.49.74 |
| Verbatim 52X CDR Data CD | 39.25X | 79.49.74 |
| Mitsubishi 32X CDRW Data CD | 29.73X | 73:43.00 |

One of the last tests we reserved for the CR52-M was the overburn media test. We used high quality PNY 48X 80min Type 6 CDRs, but sadly, it only obtained 82.51min of burn time. Even more disappointing, our drive locked up and would not let us kick the disk out. Instead, it just continued to blink and read the disk. Only a restart would eject our disk. While this is not an uncommon error in the optical media, we would have liked some error correction on MSI’s behalf. Below are the results that we obtained from our overburn test.

For those interested, we also took a measurement of Full Erase and Quick erase in Nero. For a 700MB Mitsubishi 32X CDRW, we obtained 3:20 for a full erase, and 0:26 for a quick erase. This makes it one of the fastest drives available strictly concerning erase times.

Kristopher,Why would it be ununsual that I contact you?
I'm not talking about the start/stop times in the read tests. I'm talking about the writing tests.
Nevermind.. I see you have a few Nero screenshots showing the writing times. I didn't see those before.

#9: The "dummy" CDs are the ones created in CD Speed.lan,
while I do commend your criticism, I find it slightly unusual you did email me. In all honesty, I never recorded the start/stop times of the CD Speed tests. I did record the start/stop burning speeds if you would like me to just post those.
Cheers,
Kristopher

Please add writing times to your writing tests. The average writing speed is not an accurate indicator of how fast a drive is. It can take longer to write leadin/leadout or run media tests.Anonymous User - Saturday, September 13, 2003 - link
Edit for previous post: I meant Nero CD/DVD Speed's test disc. Sorry.Anonymous User - Saturday, September 13, 2003 - link
I think that a test should be done using Nero Infotool's test disc so that people can compare results with their own drives. Or is the "dummy file" test made with it?Just a comment: These drives are slightly underrated. I have a Lite-On 52327S and it reads and writes at 53.55x at 82min. I'm sure this would rise slightly with a 99min CDR.

the shorter form factor is a good thing in my opinion, as i have had a couple cases that couldn't have standard length cd-rws mounted in the bottom 5.25" bay as the back of the drive would hit a capacitator on the moboJeff7181 - Friday, September 12, 2003 - link
Two articles a day? Sounds GREAT to me =)I've even had a hard time finding 24X CDRW media... I guess I'm looking in the wrong places because I'm not willing to pay oodles of money for CDRW's when I have a few spindles of CDR media, totaling about 175 CDR's that I didn't pay over $10 for.
With CDR media being SO cheap... is CDRW media really even necessary? Packet writing isn't that great cause you need the packet writing software to read and write to them... and why bother erasing an old scratched CDRW disk when you can pull out a brand new CDR disk that only costs you pennies?

It seems like eveyone is selling Lite Ons these days. And since when is MSI a big wheel in optical? As far as I can tell they have done nothing but sell rebadged LiteOns with slight apperance mods - just like Sony, TDK etc.etc. Does anybody else besides LiteOn and Sanyo/Plextor actually manufacture their own designs any more?.bh.

Our good friends Mitsubishi Chemical make 32X. Pretty much the best you can buy but in all honesty, not worth an upgrade from an existing drive. If you were looking into buying a new system, then I would consider the CD52-M.Aga I have a neat optical drive I will post in the next day or two. Our schedule for the next 3 weeks is full =) We might have to start posting 2 articles a day.

I think Anand is getting the Athlon 64 reviews ready. His coloumn in this month's CPU magazine mentioned September 23rd at the end of the article. Other than that, I haven't heard anything from him either.One question though, is there 32X CDRW media available readily? Last I checked, 12x and 16x is used most widely for CDRW use because the 24x and higher cost more to the end consumer.
